Patent Images
1. A method for coating and/or partial extrusion-coating of flexible, elongated products, whose surface has a material-conditioned nonstick characteristic, the method comprising:
- activating at least a portion of the surface of the product by a plasma treatment; and
applying flowable materials to the activated surface area under the influence of heat and/or pressure as a coating, with complete or partial coverage, or as a formed part.

Abstract
In order to coat and/or partially extrusion-coat flexible, elongated products, such as electrical cables or wires, and also pipes, tubing or hoses, whose surface has a material-conditioned nonstick characteristic, such as polytetrafluoroethylene, the surface of the product is wholly or partially activated (structured) through a plasma treatment and then flowable materials are applied to the activated (structured) surface area under the influence of heat and/or pressure as a coating, with complete or partial coverage, or as a formed part.
